Though that is... not all the entry points are available to be entered from safely.

For example, the screen image for Galactic Center only shows 4 of the 8 entry points not covered by the blackholes. If you by chance entered at one of the other 4 points covered by the blackholes, you might have a chance of dying?

Also brings up the question of which entry point he came in from. (unless he sublighted, like Syn stated)
